Both CPAN and CPANPLUS basically just parse the output of Makefile.PL
(or Build.PL) and then go looking for an identifier matching those
names.
An "identifier" is the thing in the left column of the index (e.g.
$cpan/sources/modules/02packages.details.txt.gz)

Turns out the optimal technique is to put it in reverse and gun it.
